“The assets sale process started in December 2014. The offer was directed at selected strategic investors,” a source said, according to the daily.

Among parties potentially interested in Newag, Puls Biznesu named Alstom, Bombardier, as well as Skoda Transportation and Swiss Stadler.

“I will consider concrete proposals if they appear,” Jakubas told the daily.

Newag shares rose almost 10 percent last year, owing to good prospects for the company in a country that invests billions of dollars in rail infrastructure, while the broader Warsaw bourse index WIG was almost unchanged. (Reporting by Marcin Goclowski; Editing by Prateek Chatterjee)
